:PAs'rnUnIzA'rIoN APPARA US.

Be it known that I, ANDREW P. .MURRAY, of Toledo, Lucas county, Ohio, acitizen of the United States of America, have invented new and usefulPasteurization Apparatus, of which the following is a specification. i.3 a 1 r i This invention relates to the temperature control treatmentof liquids, more particularly in containers.

This invention has utility when 1incor- 3 porated in continuous outputinstallations,

features of the charger;

as in the pasteurization of milk.

Referrlng to the drawings:

Figure 1. is a side elevatlon, with parts broken away of an embodimentof the 111- vention in an apparatus for the continuous pasteurization ofmilk in bottles;

Fig. 2 is a transverse section of the apparatus of Fig.1, nearthe leftend thereof; Fig. 3 is a fragmentary plan view of the charging end ofthe device ofFig. 1;: i

Fig. 6 is a view similar to Fig. 1 of an adaptation of the invention toless fragile containers, asmilk cans;

Fig. 7 is anelevation of the charging end of the device of Fig. 6; and IFig. 8 is a fragmentary plan view of the device of Fig. 7. a

The. bottle filler 1, in its operation maypass thefilled containers orbottles to the. capper 2, from whence along the Way 3,

the bottles 4 are successively shoved in pairs over the sectional way5,6. As the third pair of bottles is moved intoposit1on on forward sideby the bar 7, and on .theafter sideby the linkage, theleading' bottle 41s thrust against the abutment 8against the action of spring; 9, andthrough the angular arm 10from the abutment 8, rocks the arm 11 on theshaft12 mounted in the support 18. Fast on each shaft 12 is a waysection 5, while extending. from eaoh arm 11 is a link 14 engaging a waysection 6. *The several arms 11 are connected by the links 15.

This quick thrust action as the third pair of bottles 4 is shoved uponthe sectional way 5, 6, causes this transverse wayto open Specificationof Letters Patent. PatQntedjJ 11116 24, 1919. Application filed May 3,1917. Serial No. 166,110. i

downward under each bottle that it may settle down into a seat 16in thetreatment way or endless conveyer 17 continuously driven at a slow speedby the motor 18, so that at each supply of six bottles, of the desiredcharge for a transverse row of conytainers, a row of seats may be inregistry therebelow for recelving the containers. As

theqconveyer slowly travels and the bottles 4 move clear of theopenedsections5,

6, the-spring 9 recovers to .bringthe ways into closed position for thereceiving of the next charge of bottles.

The seats 16 of the conveyerl? are in transverse and also in alined.longitudinal rows. ;.The parallel longitudinal rows conduct thebottles 4through the flexible flaps 19 of thecurtains 20 at the entrance, at thedischarge, and between the differenti stages a of treatment in thehouslng for the closed.

treatment lanes including the superposed tanks-21, 22, 23,, 24, 25, 26.Theibottoms of these tanks have relatively alined shower means for.multi-stage temperature control provision for each lane, in the form ofthe shields 27 protect ng the topson closure sections of the containersfrom action by the temperature controllingsubstance or wash from thetanks. From. each S1d60f the shield and. directed toward each other is asheetor film projecting nozzle28servingeffectively to envelop the entirelateral extent of. the. container below the protected top region.Thisliquid temperature controlling envelop sheet then passes through theopenwork of theconveyer 17 to the respective spill tanks 29, .30, 31,32, 33,34, therebelow to be conducted by a line .35 to a sewer 36, forwaste or desired selective or regenerative re-use. In bottle treatmentfor milkpasteurization, the tank 21 may provide preheating liquid; thetank 22 heating liquid; the tank 28 liquid to hold the milk heatedgthe;tank 24 liquid for precooling;

the tank 25 brine forcooling; and the tank 1 26 for washing the brineoff the bottles.

In the further trayelof this endless conveyer 17, normally sustained byits rollers 37 on theqtracks 38 between .its terminal sprocket wheels39, 40, the tops of the bottles 4 enga e the bar 41 to preclude forwardtilting. ccordingly in this forward travel, the tops of the bottles areheld back and the bottles move bottom downward along the chute 42. Thebottles of cooled pasteurized milk are thusv delivered top side upint'othe crates 43, which crates are readily shiftable on the rollers 44-intoproper bottle. receiving position.

There is by the above installation. a continuous handling of thepasteurized product without exposure to contamination after the andthenwashing suflices.

For larger Containers, as ten gallon milk cans 45, these may be chargedupon an endless'conveyer 46, say in gangs of four deposited in theconveyer seats 47 for parallel longitudinal row alinen'ient. Rocking ofthe handle 48, will serve through the link 49,

rock shaft 50, levers 51, cables 52, to lift the several counterweighted doors 53 between the treatment stages of the housing. The

' conveyer 46 may then be moved ahead the proper distance for recharglngby turn ng the'handle 54, which through the pinion-55, and gear 56actuates the conveyer sprocket 57 that the conveyer 46 may have itsrollers 58 travel along the ways 59 and carry the containers 45 one stepforward. Handle 48 'Inay'then be swung up for closing the various doors53, and the cans for a succeed ing charge supplied.

The tanks 60, 61, 62, 63, 64, supply respectively liquid for heating,holding heat,

without contamination.

precooling, cooling and Washing the cans. These form'portions of thehousing and shield the upper or. filling portions of the cans 45.fromthe washings, as the pairs of sheet filmnoz'zles envelop each can with asheet of liquid over the entire sides at the stopping positions belowthe shielded upper portions of the cans. The nozzles 65 are supplied bythe ducts 66 with the flow from the respective tanks controlled by valve67.

. The open conveyer 46 allows the wash to pass therethrough to thevarious spill ways 68, 69, 70', 71, 72, for conduct by the Ways 73 tosewer 7 5, or such desired return as may be acceptable for 're-use ofthe liquids. The filled treated liquid containing cans passing from thehousing, as a new charge is supplied at the opposite end, may be removedas ready for storage or transport between the rows of shower meansserving lVhat is claimed and it is desired to secure by Letters Patentis:

1. An endless conveyer for parallel rows of containers having tops, ahousing providing lanes alined with said container rows, and showermeans for said relatively movable containers, said means having animporforate portion enveloping the containeriiops to shield said topsduring the travel of the containers therethrough.

2. An endless conveyer provided with alined seats for parallel rows ofcontainers, and housing means for said conveyor providing a continuouslane for each row of relatively movable containers, there beingshowerssupplied by said housing means, said shower means providing adownwardly open channel at each lane into which channels the containertops may protrude, the channel formed by the shower means being providedby the housing means and serving as a shield for the container tops.

3. A series of tanks, parallel rows of alined shower means therefromdisposed to form downwardly open channels, an endless conveyer belowsaid shower means having container seats for containers provided withtop projecting to travel in the channels of the shower means, anddriving means for the conveyer efiecting the travel of the containers asto the'shower means, said channels 90 as shields forthe container tops.

4. Pasteurization apparatus comprising a stationary horizontal uide,conveyer means coacting longitudinal y of said guide to providelongitudinally extending series of seats for the bottoms of containerswith the tops of the containers extending upwardly therefrom, saidseries of seats being disposed to form transverse rows as to the guide,shower means in longitudinally eX- tending rows between the containersin the seats for showering directly upon the container in said seatsbelow the tops of the containers with clear showerless regions pro videdto coincide with the longitudinal rows 'at the container tops, and meansfor actuating the conveyer for shifting the containers horizontallyalong the longitudinal rows in coactionwith the shower means on thesides of the containers, the tops of said I containers being shielded bythe position of the shower means to keep the top of the containers inthe clear showerless region of the longitudinal rows of the seats.

In testimony whereof I ailix my signature.
